Elon Musk continues with the intention of making Twitter profitable at all costs, and if necessary, he will get money for it from under the rocks. Its latest measure in this regard is that the payment is one of the security measures of the service to protect user accounts.
We’re talking about two-factor authentication, two-factor authentication… It doesn’t matter what you call it, it’s the same thing. On Twitter in Spain it’s called two-factor authentication and it works exactly as you imagine: activating a second layer of security to verify that whoever logs in is who they say they are.
Therefore, if two-factor authentication is activated, after entering the username and password, the user will be prompted for a second step for identification. And this second step can be done in three ways: using a text message, using an authenticator application, or using a security key.
All users who trusted SMS to log in to Twitter did until March 19, 2023 disable this option or subscribe to Twitter Blue, the social network’s payment plan, to continue enjoying this feature.

Of course, controversy has flared up around this new measure, but the truth is that it is not particularly negative. What’s more, of the three ways Twitter allows you to use two-factor authentication, this is text messaging is the least recommended security levelas experts have been warning for years.
And it’s not even the most accessible: although only the most timid and cautious walk around with a security key – a physical device – in their pocket, Much safer than receiving an SMS on a mobile phone and just as convenient is using a verification application like Google Authenticator or Microsoft Authenticator, to name two well-known examples.
In short, if you use Twitter SMS two-factor authentication and aren’t willing to jump through the Twitter Blue hoops, you’re already headed to service preferences make a change. You will appreciate it in more ways than one.
